San Diego is one of the most concentrated military communities in the United States, and if you have orders here, you are about to find out why. PCS stands for Permanent Change of Station, the military term for moving from one duty station to another. This 2026 guide covers the four major installations in the San Diego cluster — Naval Base San Diego, Naval Base Coronado (including Naval Air Station North Island), Marine Corps Air Station Miramar, and Marine Corps Recruit Depot San Diego — and what military families need to know about where to live, how housing pay works, schools, healthcare, and daily life in Southern California.
A PCS to San Diego comes with a lot of moving parts. Our goal is to make the base side of that equation feel clearer.
What and Where Are the San Diego Military Bases?
San Diego County is home to several major installations serving the Navy and Marine Corps. Four of the largest and most active are the focus of this guide.
Naval Base San Diego (32nd Street)
Naval Base San Diego sits along the San Diego Bay waterfront at 32nd Street, which is how most service members and local residents refer to it. According to the installation's official page, Naval Base San Diego is homeport to the Pacific Fleet Surface Navy with 60 U.S. Navy ships and two auxiliary vessels, including USNS Mercy. The base is also home to more than 200 tenant commands and spans over 1,600 land acres and 326 acres of water along San Diego Bay.
Naval Base Coronado and NAS North Island
Naval Base Coronado is a cluster installation that includes Naval Air Station North Island on the Coronado peninsula, Naval Amphibious Base Coronado, and several outlying facilities. According to the official NAS North Island history page, North Island was commissioned a naval air station in 1917 and was granted official recognition as the "Birthplace of Naval Aviation" by a resolution of the House Armed Services Committee on August 15, 1963. North Island has been a continuous homeport for Pacific Fleet carriers since the USS Langley arrived in 1924. Today it serves as a major hub for naval aviation squadrons and carrier air wings.
Marine Corps Air Station Miramar
MCAS Miramar is located about 12 miles north of downtown San Diego. According to the official MCAS Miramar website, it is the West-Coast headquarters of Marine aviation and home to the 3rd Marine Aircraft Wing (3d MAW), with over 15,000 service members and their families from all branches calling the San Diego area home. The station's mission is to maintain and operate air station facilities while providing services, material support, and training venues that promote combat readiness and support the missions of 3d Marine Aircraft Wing and other tenants.
Marine Corps Recruit Depot San Diego
MCRD San Diego is located near downtown San Diego, just north of the airport along the bay. According to the depot's official mission page, MCRD San Diego and Western Recruiting Region makes Marines by recruiting quality young men and women and transforming them through the foundations of rigorous basic training, our shared legacy, and a commitment to our core values, preparing them to win our nation's battles in service to the country. MCRD San Diego draws recruits from the western two-thirds of the United States through an intense 13-week training program.
Where to Live When PCSing to San Diego
San Diego is a large metro, and where you live matters. Your best neighborhood depends on which base you are reporting to, your commute tolerance, your budget, and what kind of community you want around you. Most of the commute times below center on Naval Base San Diego (32nd Street), which is a common reference point. If you are reporting to Miramar, add roughly 10 to 15 minutes to communities south of the base; if you are at Coronado or MCRD, adjust accordingly.
On-post housing options exist at several installations. Ask your sponsor and the housing office early about wait times and eligibility.
Approximate one-way drive times to Naval Base San Diego (32nd Street). Commute times vary with traffic and which base you report to. See note below.
Chart note: Times above center on Naval Base San Diego at 32nd Street. Commutes to NAS North Island, MCAS Miramar, or MCRD San Diego will differ by location.
National City
National City sits just south of downtown San Diego, directly adjacent to the 32nd Street waterfront. It is one of the closest communities to Naval Base San Diego, with typical drive times under 10 minutes on a normal day. Housing costs tend to run lower than neighborhoods inside San Diego proper, making it a practical choice for families who want to stay close to the base.
Coronado
The island city of Coronado is on the far side of the bay bridge, roughly 15 minutes from 32nd Street and a short drive to NAS North Island and Naval Amphibious Base Coronado. It is a popular choice for Navy aviation families and special operations personnel stationed at Coronado. Housing on the island is expensive; many families look at Point Loma or Imperial Beach for more affordable options near the same bases.
Point Loma
Point Loma is a peninsula west of downtown with a strong military history and a quiet, neighborhood feel. It sits about 12 minutes from 32nd Street and is convenient to both the 32nd Street waterfront and the Coronado installations via the bridge. It has good schools, parks, and walkable commercial areas, and many Navy families have called it home for generations.
Chula Vista
Chula Vista is a large city immediately south of San Diego, about 18 minutes from 32nd Street and well-positioned for families at National City or the southern end of the base. It offers more housing square footage for the price than neighborhoods inside city limits, a wide range of schools, and easy freeway access. It is one of the most popular choices for San Diego military families.
Imperial Beach
Imperial Beach is at the southern tip of the bay, roughly 20 minutes from 32nd Street and close to the Naval Outlying Landing Field and Coronado area. It is a small, laid-back beach community with lower housing prices than much of the metro. It appeals to families who want the beach lifestyle without the cost of Coronado proper.
El Cajon
El Cajon sits inland to the east, about 22 minutes from 32nd Street. It offers larger homes and more land for the dollar and is positioned between the coast and the mountains. Families stationed at Miramar sometimes find El Cajon a convenient middle ground between the base and the wider metro.
Santee and Mira Mesa
Santee is a family-friendly community in the East County, roughly 25 minutes from 32nd Street but closer to Miramar. Mira Mesa is a large neighborhood in northern San Diego, also about 25 minutes from 32nd Street but just minutes from MCAS Miramar. Both are popular with Marine families assigned to the air station. Mira Mesa in particular has a long history as a go-to neighborhood for Miramar personnel, with affordable housing relative to coastal areas and strong community ties to the base.
San Diego BAH and the Cost of Living
If you live off base, the military helps cover housing through BAH, which stands for Basic Allowance for Housing. BAH is a monthly, tax-free payment based on three things: your rank, whether you have dependents, and your duty station's Military Housing Area, or MHA. An MHA is the geographic zone the Defense Department uses to set local housing pay rates. All four installations in this guide share the San Diego MHA.
